5. Commissioning

5.1 Check proper connectionObserve the relevant standards and regulations that have to be observed for installation and connection as well as the operating manual of the respective device.

5.2 Before switching onBefore switching on think carefully about these questions:

1. Does the connected supply voltage correspond to the nameplates' informa-tion?

2. Are you sure that the nominal insulation voltage of the measuring current transformer has not been exceeded?

3. Does the measuring current transformer's maximum current correspond to the nameplate information of the connected device?

5.3 Switching onAfter switching on, proceed as follows:

1. Connect the supply voltage.

2. Set the bus address/IP address.

3. Set the CT transformation ratio (for each channel).

4. Change the measuring current transformer's counting direction, if required.

5. Set the nominal voltage (line-to-line voltage ULL).

6. Select wye connection or delta connection.

5.4 SystemThe universal measuring device PEM575 can be programmed and queried via Modbus RTU. For details refer to „chapter 10. Modbus Register Map“ or the Internet www.modbus.org.

Commissioning

In addition, it is possible to integrate the device into Bender's own BMS (Bender measuring device interface) bus protocol via additional communication modules. In this way, communication with (already existing) Bender devices for device parameterisation and visualisation of measured values and alarms can be achieved.

Help and examples of system integration can be found on the Bender homepage www.bender.de or you can contact our Bender Service for personal advice (see „chapter 1.2 Technical support: Service and support“).

Operation

6.5 LED indicationThe universal measuring device features two red LEDs on its front panel: kWh and kvarh.The two LED indicators are used for the indication of kWh and kvar, if the EN PULSE function is enabled. The setting can be carried out in the setup menu using the buttons on the front or via the communications interface..The LEDs flash each time a certain amount of energy is reached (1 kWh resp.1 kvarh). The amount of energy displayed corresponds to the amount of energy measured by the measuring device. In order to determine the actual amount of energy, the flashing frequency can be calculated from the CT ratio and the pulse constant.

6.6 Standard displayThe universal measuring device automatically shows the default display screen, if there is no button pressed for 3 minutes in the Setup mode.

7. Application/inputs and outputs

7.1 Digital inputs (DI)The device features six digital inputs which are internally operated with DC 24 V.Digital inputs are typically used for monitoring external statuses. The real-time statuses of the digital inputs are available on the front panel LC display as well as through connected system components. Changes in external statuses are stored as events in the SOE log in 1 ms resolution. One of the digital inputs can be programmed to receive pulses for the synchronisation of the demand measurement. The setting is to be carried out via register 6021 (page 117).Digital inputs can also be used as external time synchronisation pulse (see page 84).

7.2 Digital outputs (DO)The device features three digital outputs. Digital outputs are typically used for setpoint alarming, load control or remote control applications.Examples:

1. Manually operated from the front panel (Chapter 6.8 Setup configuration via the front panel)

2. Operation via communications interface (Chapter 10.19 DOx output control).

3. Control setpoints: Control actions in response to a specific condition (Chapter 7.6 Setpoints)

4. Digital outputs triggered by logic modules(Chapter 10.12 Logic module).

5. Triggered by undervoltage or overvoltage(Chapter 9.4 Undervoltage/overvoltage setpoint (sag/swell setpoint)).

6. Triggered by transient events(Chapter 9.5 Transient events setpoint).

7. Control via digital inputs

Priority: Front panel control has a higher priority and overwrites the other applications.

51PEM575_D00016_01_M_XXEN/05.2016

Application/inputs and outputs

For a general alarm, all setpoints can be programmed to control the same digital output. However, if the user intends to generate a control signal in response to a specific setpoint condition, each DO may be controlled by only one source.

7.3 Energy pulsing outputThe two LED pulse outputs are used for kWh and kvarh indication, if the function EN PULSE is enabled. Energy pulsing can be enabled from the front panel through the EN Pulse setup parameter or via the communications interface.The LEDs flash each time a certain amount of energy is reached (1 kWh resp. 1 kvarh). In order to relate the flashing frequency to the amount of energy, the transformation ratios and the pulse constant have to be considered.

7.4 Power and energy

7.4.1 Basic measurementsThe PEM575 provides the following basic measurements with a 1 second update rate: three-phase voltages three-phase currents three-phase power three-phase power factors λ Neutral current Frequency Energy import and export Voltage and current phase angles

7.4.2 High-speed measurementsIn addition to the basic measurements, the PEM575 provides the following high-speed measurements: three-phase voltages (10 ms) three-phase currents (20 ms) three-phase power (20 ms) three-phase power factors λ (20 ms) Neutral current (20 ms)

7.4.3 Voltage and current phase anglesPhase angle analysis is used to identify the angle relationship between the voltages and currents of the three line conductors.

7.4.4 EnergyBasic energy parameters include active energy (import, export, net energy and total energy in kWh) reactive energy (import, export, net energy and total energy in kvarh) as well as

reactive energy related to the quadrants Q1…Q4 apparent energy (Sges in kVAh)The maximum value to be displayed is ± 999,999,999,99. When the maximum value is reached, the register will automatically roll over to zero. The counter value can be edited via software or through the front panel, password required.

7.5 Demand DMDThe demand is defined as an average consumption value over a fixed demand period. PEM575 supports the "Sliding windows" demand calculation; in addition to the demand period also the demand cycles, which are to be considered, are specified here. The following parameters can be set: Synchronisation mode

– SLD internally synchronised to the PEM's clock– SYNC DI externally synchronised to a digital input that has been program-

med as a demand synchronisation input (DI function = SYNC DI) Demand cycles (1…15)

In Trigger mode 1, a fixed time can be set in seconds to delay the start of the measurement (triggered by timer). Example: "300" means that the recording will take place at 5 minutes after the DR is enabled. In order to obtain evaluable results, the programmed value of the recording offset parameter should be less than that of the recording interval parameter.

For Trigger mode 2, recording delay is ignored.

8.5 Waveform recording (WFR)The PEM575 provides two waveform recorders capable of recording waveforms independently from one another. The total capacity of WFR 1 and WFR 2 is 32. Each waveform recorder can simultaneously record 3-phase voltage and current signals at a maximum resolution of 256 samples per cycle. Waveform recorders can be triggered by Setpoints Undervoltage/overvoltage (sag/swell) Transient events Communications interface (manual)

During this process the control via communications interface has the highest priority. Other WFR triggers will be ignored until recording is completed.

Each WFR log has a capacity of 32 entries. If there are more than 32 entries, the newest entry will replace the oldest entry on a first-in-first-out basis: Der 33rd entry overwrites the 1st entry, the 34th the 2nd etc.WFR data is stored in a non-volatile memory and will not suffer any loss in the event of power failure.

The programming of the waveform recorder log is only supported by the communications interface. For details about the applied registers and their data structure refer to page 133. The following set-up parameters are supported:


1 Number of measurements 0…32 (entries)

2 Number of samples per cycle 16, 32, 64, 128, 256 samples

3 Cycles per record 320, 160, 80, 40, 20 cycles

4 Number of cycles before the event 0…10 cycles

77PEM575_D00016_01_M_XXEN/05.2016

Logging

The total capacity of WFR1 and WFR 2 is 32 entries. The valid formats from the number of samples per cycle and number of cycles are:

16 x 32032 x 16064 x 80128 x 40256 x 20

When the WFR format is 256 samples per cycle, the "number of pre-fault cycles" can only be set between 0 and 5.

Fig. 8.1: Waveform recording displayed in CP700

8.6 Power Quality log (PQ log)The PQ log can store up to 1,000 events such as undervoltage/overvoltage and transients. The newest event will replace the oldest event on a first-in-first-out basis: If there are more than 1000 entries, the 1001st entry will replace the first one, the 1002nd will replace the second one etc.Each entry includes the event classification, its relevant voltage values and a timestamp in 1 ms resolution. The PQ log can only be read via the communications interface. For details about the applied registers and their data structure refer to page 138.The PQ log can be reset from the front panel or via the communications interface.

10. Modbus Register Map

This chapter provides a complete description of the Modbus register (protocol version 6.0) for the PEM575 series to facilitate access to information. In general, the registers are implemented as Modbus Read Only Registers (RO = read only). with the exception of the DO control registers, which are implemented as Write Only Registers (WO = write only).The PEM575 supports the 4-digit addressing scheme and the following Modbus functions.

1. Holding register for reading values (Read Holding Register; function code 0x03)

2. Register for DO status setup(Force Single Coil; function code 0x05)

3. Register for device programming(Preset Multiple Registers; function code 0x10)

4. Read general reference(Read General Reference; function code 0x14)

For a complete Modbus protocol specification, visit http://www.modbus.org.

Explanatory comments relating to the read reference(function code 0x14)The Modbus function code "0x14" is used to access the stored data from the data recorder log (DR log) energy log power quality log (PQ log) waveform recorder log (WFR log)

5) The alarm register 0087 indicates the various alarm statuses (1 = active, 0 = inactive). Details of the alarm register are shown in the following table:

Tab. 10.3: Bit sequence alarm register (0087)

6) The SOE pointer points to the last entry added. The event log can store up to 512 events. It works like a ring buffer according to the FIFO principle: The 513rd value overwrites the first value, the 514th the second one and so on. The event log can be reset in the setup parameter menu (see page 46).

7) Der PQ log pointer points to the last value added. The PQ log can store up to 1000 events. It works like a ring buffer according to the FIFO principle: The 1001st value overwrites the first value, the 1002nd the second one and so on. A reset of the PQ log can be carried out in the set-up parameters (see page 46).

8) The PEM575 utilises two waveform recorders (WFR). Each WFR has its own pointer that indi-cates the most recently added entry in each case. The two WFR together can store up to 32 events. It works like a ring buffer according to the FIFO principle: the 33rd entry overwrites the first value, the 34th the second and so on. The WFR log can be reset via the communica-tions interface.

Tab. 10.33: High-speed data recorder register structure

Notes: table 10.33

1) High-speed data recorders can be triggered by a timer (the internal clock) or a setpoint. In trigger mode 2 when the setpoint goes active, the recorder starts to record, and when the setpoint becomes inactive, the data recorder stops.

2) For high-speed data recorders, the recording mode only supports stop-when-full without overwriting other data.

3) Recording delay: The delay in seconds is specified when a measurement is to be started in Trigger mode 1 (triggered by timer). Example: When the delay is set to "300", the measure-ment will start 300 s (= 5 minutes) after the timer period has elapsed. In order to obtain eval-uable results, the programmed value of the recording delay parameter should be less than that of the recording interval parameter. For Trigger mode 2, recording offset is ignored.

4) For high-speed data recorders only the parameters 0…28 from table 8.3.2 can be used.







The data recorder only becomes active, if the offset entries +1, +2, +3and +6 marked in the table are non-zero!

Modifying an offset parameter will clear the DR log and reset the pointer to 0.

1) The standard data recorder can be triggered by a Timer (the internal clock) or by Setpoint. In trigger mode 2 when the setpoint goes active, the recorder starts to record, and when the setpoint becomes inactive, the data recorder stops.

2) Recording delay: In Trigger mode 1, a fixed time can be set in seconds to delay the start of the measurement (triggered by timer). Example: When the delay is set to "300", the measure-ment will start 300 s (= 5 minutes) after the timer period has elapsed. In order to obtain eval-uable results, the programmed value of the recording delay parameter should be less than that of the recording interval parameter. For Trigger mode 2, recording delay is ignored.

3) For standard data recorders all the measured quantities 0…328 from table 8.3.2 can be used.

10.14 Waveform recording (WFR)The PEM575 provides two waveform recorders capable of recording waveforms independently from one another (waveform recorder WFR1 and WFR2). The total capacity of WRF 1 and WFR 2 is 32.

The data recorder is only operational when the offset entries +1, +2, +3and +6 are all non-zero!

Modifying an offset parameter will clear the DR log and reset the pointerto 0.

Each waveform recorder can simultaneously record 3-phase voltage and current signals at a maximum resolution of 256 samples per cycle.

Tab. 10.35: Waveform recording register

Notes on table 10.35: 1) The total capacity of the waveform recorders is 32, i.e. the total of the number of measure-

ments in WFR 1 WFR 2 must be ≤ 32. The waveform recorder is disabled when register 7600 is set to 0.

2) Valid WFR formats (number of samples/cycle x number of cycles) are 16 x 320, 32 x 160, 64 x 80, 128 x 40 and 256 x 20.

3) When the WFR format is 256 x 20, the number of pre-fault cycles is 0…5, otherwise the range is 0…10.

The waveform recorder data contains the values of the secondary side. The voltage data returned is 10 times of the actual secondary voltage and the current data is 1,000 times of the actual secondary current. The voltage and current values of the primary side are calculated as follows:Uprimary = Usecondary x voltage transformer transformation ratio/10Iprimary = Isecondary x CT transformation ratio/1,000

2. UNIX-time register 9004

When sending the time via Modbus communications, care should be taken to only write one of the two time register sets. All registers within a time register set must be written in a single transaction.If all the registers 9000…9004 are set, both timestamp registers will be updated to reflect the new time specified in the UNIX time register set. Time specified in the first display format will be ignored.

Optionally, the register 9003 displays milliseconds. When broadcasting time, the function code has to be set to 0x10 (Preset Multiple Register). Incorrect date or time values will be rejected by the universal measuring device.

In order to query the current DO status, the register 0086 have to be read out.PEM575 supports the execution of commands to the outputs in two steps (ARM before EXECUTING): Before sending an open or close command to one of the outputs, it must be activated first. This is achieved by writing 0xFF00 to the appropriate DO register. If an "Execute" command is not received within 15 seconds, the output will be deactivated again.

Each command to be executed sent to an output not being activated before, will be ignored by the PEM575 and returned as an exception code 0x04.
